Claims.
AThis invention relates to a pleating machine and has particular relation to the making of sausages. The invention will bedescribed primarily in its relation to the particular art of making sausages, but it is to be understood that this particular description is adopted for purposes of expediency and does not constitute a limitation.
For hundreds of years sausages have been made by filling a tubular casing with foodstuffs. The casing has been tied at one end with string, filled with the food product, such as sausage meat, or cheese, and has then been tied with string at the other end. In United States Patent No. 2,493,063, the art was shown how to seal a sausage casing in a better and more sanitary way by employing an eyelet seal. In that invention, the end of the sausage casing, which is a simple tube of edible transparent material such as regenerated cellulose, is flattened at one end, pleated, gathered, and the eyelet is passed over the gathered pleats and clamped upon them. Heretofore, the pleating was done by hand or by use of simple pleating jaws. That method of pleating had a number of disadvantages, among which were these, that it sometimes tended to weaken the material of the casing, that it was time and labor consuming, and that it could not be done as rapidly as the pleated tubes could be eyeleted.
It is an object of this invention to pleat tubular material of sausage casing type at a rate equal to that at which the eyelets can be applied.
Another object is to mechanically pleat tubes without straining the material.
A further object is to reduce the cost of the pleated casings by increasing the efliciency with which they are produced.
Another object of the invention is to employ the new machine and the new process in all elds of industry where pleating is accomplished, including among others the clothing industry, and to accomplish the pleating even upon delicate material without strain.
.The objects of the invention are accomplished, generally speaking, by carrying out the pleating progressively, which includes one pleat after another and also pleating in successive groups. The principles of the mechanism by which this is accomplished are set forth by means of illustrative embodiments hereinafter. It is to be understood, however, that the drawings are for purposes of illustration only and do not constitute a limitation of the invention, reference for this latter purpose. Abeing primarily to the appended claims.

Fig. 1v1 is a plan view of a part of the sprin of Fig. 6; f
Fig. 12 is an end view of a rubber spacer'of Fig. 6.
The structure of Figs. 1 and 2 represents a preferred embodiment of the invention. In these gures the power linkage and frame are omitted in` order to raise the operative parts to a larger scale. The power linkage and frame may be of the kind shown in our prior application on the sealer, or of anyv other satisfactory press type adapted to move one or both of a pair of jaws toward and away from each other to engage flexible material placed between them. Such mechanical m-otions are generally known and may satisfactorily be of manual or power operated reciprocating type.
In Figs. 1 to 3, a lower xed iframe member provided with a square hole in which `is received a square dowel I6 of hollow conformation open-A ing upward and cl-osed at its lower end by screw threaded cap I8. The hollow part of the dowel is reduced at its upper end to form a limit stop I9. The dowel is held in the frame 'member by a set screw 2li. At its upper end theA dowel is externally'reduced to form a shoulder y2| `upon which rests the lower jaw 22. The end 23 of the dowel exteruisV into the jaw 22 and is temporarily or permanently aixed thereto.
The jaw 22 is channel shaped, as seen in Fig. 3, having elevated ends and a reduced mid-portion of rectangular shape in which a block 24 lits.
The hollow at the top of the dowel is square and admits atting square pin or stud 25 upon which the block is xed. The stud extends into the larger part of the hollow and is provided with a head 26. that cooperates with shoulder I9 to limit Islsr its upward motion. The head is shown as a washer held on by a nut. Bearing at one end upon the washer 26 on pin 25 and at the other upon the cap I8 is a spring 21 that biases the block outward to a position in advance of the raised ends of the jaw, and permits the block to be retracted to a position even with the top of the jaw when enough pressure is applied to overcome the strength of the spring.
Mounted in the jaw and in the block, which is efectually a movable part of the jaw, are pleating teeth Sli-3|. These teeth are long, narrow, nat sided, and have ends 32 of sweeping curvature leading to flat portions 33 of considerable length. The construction of these teeth reduces the power required for pleating.
Attached to the back of jawY 22 by screws 3 4A is a plate 35 that extends above the most. elevated position of teeth 3| and covers the gap back of the lower pleating teeth and the upper teeth.
TheY upper support 4 9 is reciprocable. It has a hole 4i in which asquare hollow dowel 42 is received. The dowel 'carries upper jaw 43 ofA construction similar to that; ofv the lower jaw, and similarly attached. The hollow of the dowel encloses astud 44 having a cut outportion-45 forming limit stops by contact with screw 46 that serves as an abutmentY to limit its motion. A spring 41 within the dowel presses upon the stud and forces the block 48 carried by the stud downward in advance of the other parts of jaw 43. Teeth 551-50, of like construction, arermounted in, jaw 43 and blocl; drain interdental alignment `with* teeth 30-3 l In separated position the teeth are spaced-sufiicientlyv to admit:v the material to be pleated, as shown in Fig. 2.
The material is alignedby a guide 60 carried by the lower frame member I5, which is composed i,
of a plate 60 having an opening 6I 4having extensions- {i2-63;
Inthe extensions are two `movable guide members 64M- 65; Each guide member has an outer flangre that bears against the face of plate E0,
'againstplate and, the'upper jaw is brought down; The teethEl-SI' engage first and draw the material freely past teeth 3-49 into central pleats, then the edges of the block teeth engageV the opposite blocks through the pleats7 cornpress theY springs, and force the blocks into retracted position, while the teeth Sil-ll!)l come into actionand pleat the ends of the casing.
By this conception of pleating progressively, straining the material and stretching during pleating is avoided. The result is usually best when the progressive pleating is carried out'from the center toward the ends.
A valuable alternative form of the invention is shown in Figs. 4 to 12. In those iigures the nuvmerals'IilL-'H represent upper and lower jaws either or both of which may be reciprocable. Carried by the jaws are curved springs. The
curved spring 12 of the lower jaw is a curved teeth are inserted in the slots wires 'I6 are passed through holes in the tabs to hold them in position. The spring is arcuate and"k the slots are preferably radial to the arc, aligning the teeth radially. The wires stop short of the ends of the springs in the form shown. The upper jaw is like the lower, the teeth being interdentally aligned. When the jaws are moved together the center teeth start the crimping, which proceeds thence progressively toward the ends. When the teeth engage the spring it is compressed and flattened and the teeth move toward parallelism, gathering the pleats.
The teeth may be moulded in the rubber if del sired, in which case the wires may or may not be used. A satisfactory jaw li) is iiat from end to end and has anges 'H to which the ends of the compressible springs are attached by pins 18.
In a modification of this form of the invention, shown in Figs. 6 and '7, a at steel spring 19 passes through slots in flexible rubber spacers Si and slots 82 in teeth 83'. The method of assembly is yshown in Fig. 6. One end of the spring is anchoredas at 78A', by forming an eye 84 in the end-ofthe spring, and the other end is free to-slidebetween retainers such as pins mounted in the vflanges Tl of a jaw-such as lil.
An advantage of this invention is that materialhav-ing a plurality ofplies such as a sausage casing, or a plurality of leaves, or several thicknesses of cloth, can bepleated without stretching the material because the central portion is pleated, and-the endlportionsare therefore allowed togliderwith-relative freedom between the outer teeth, being thereafter progressively gatheredin thepleat-until the operation is completed.
Another-advantage-ofthe-invention is in the speedwith-which the pleating operation is accomplished, itbeing completedy ina single stroke of the pleating-jaws. Thus, a single-machine may accomplishY the pleating-.and the sealing, a single reciprocating member may, for example, carry side by'side, pleatingandy sealing means. The operatorl may put the-tube between the pleating teeth, and-gather and withdraw the pleats in the first stroke of the machine, eyelet' the pleated end and-sealitin-the'second stroke-of the machine. Separate machinesV may also be used to accomplishrthe saine result, the pleating being completed'vin oneand the sealingV in another.
Another advantage oftheinvention is in reducing the-cost and improving theV eiiiciency of the mechanical sealing o fvtubes;
Yet another advantage of the-invention is that it particularly facilitates the pleating of tubular Vbodies by'limitingthev` deep-plaat to a very n limited width of` the .pleated materiaL'leaving the pprtionsl adjacent thereto free to assume the circular endformation thatpisV most desirable.
A" still; further, advantageof this invention is inthe, construction of the pleating teeth because, by constructing themin the form shown, but little power is requiredforpleating, whereas manytimes the power is vpressured whenthey are otherwisepnstructed: Y Y
As many apparently widely different embodimentsvo'f.A thev presentY invention may be, made without. departing from;A the spirit and scope thereon it is to fbe understood' thatthe invention is notulimitedltothe specificy embodiments, except: asdenedtin the appended Claims.
